These were the settings in use when I found my Saxon gold:
Coil: 9 inch concentric
Disc: Barely above iron
Sensitivity: Cranked up until unstable then backed off back to smooth operation
Threshold: 1:00
Tone: 3:00
Also utilized 5.75 inch concentric coil in areas such as fair sites

I also use the Tejon as one of my main machines and set it up so that my main disc is set up just at the L in Foil.I don't even use the 2nd mode nor the pinpoint feature anymore , but inexperienced users may want to. It slows me down. Ground balance slightly positive. I like Threshold at about 2 O -Clock. Tone is preference
Dig any repeatable signal . Yeah you'll get some junk but in the last two hunts I've found 15 hammies with the Tejon.
Good Luck

Tesoro DeLeon

Coil: 9" Concentric

Search Mode: Disc

Sens: As high as possible while maintaining a smooth operation

Discl Level: No more than Iron or a hair above

Regardless of reading, dig all signals, even broken ones.

Use of the larger (And also very sensitive) Tesoro 10x12" coil not recommended as it causes the machine to be very noisy and erratic.

My wife Marjo uses this machine in the U.K. and usually does very well with it.

Sensitivety - Depends on the ground. Have run it as low as 73 and as high as 99.

Disc - 6

Notch - leave at factory preset.

Number of tones - 2F

Processor - DE

I have heard that the "notch" setting has software issues. First time I used the machine, it sounded like band practice. What I was told is that if you try to notch something out, it's actually notching it in (or something like that) Best thing to do is leave it alone, it works fine. If you have changed it at all, or want to be safe, do a factory reset (turn machine off, then pull trigger and hold menu button while turning it on) It is amazing how the chatter disappears

The F-75 is gonna be a keeper in my arsenal.
Love its fast recovery, faster than any machine I've ever seen it seems to combine features I like in both my Garrett and the Tejon. Unfortunately I only had a chance to use it for a day as the crappiest weather the week we were there. Couldn't see the screen, so I figured I would hunt by sound only and therefore go with the Tejon.
Most my pals in the UK that are doing well with 'em are hunting with disc at 4
notch- factory
fast grab often
PF mode as its almost as sensitive like the JE mode, but more stable
Sensitivity as high as possible without falsing and chattering.
2 -3 tones

I believe a lot of people run the Explorer II differently. I will post how I like to run it here, so that others can see, and post how they like to run theirs.

I run it wide open, and I don't believe that is for everyone. It can suck your brains out, as you like to say.

Smart Screen always.
Ferrous mode
IM (iron mask) -16
Sensitivity-- Manual, as high as it will go and still run stable.
Gain. Set pretty high, I use 8.
Volume 10
Limits 9
Variability 7
Threshold tone and volume, set low.

Use Fast when hunting in trash, and Deep when the fields are quiet. Don't use the 2 at the same time.

This setting allows for good targets to be heard amongst the iron trash, as well as providing exceptional depth. I was pulling greenies out of the hooker field at 14 inches, which only sounded like blips of iron, until I removed a few inches of soil with my boot, and got a good signal.

Minelab Sovereign…...
Disc : Zero (fully ccw)
Notch : Zero (fully ccw)
Mode: Discriminate
Volume : 3 o'clock
Threshold : Adjust to a slight hum
Sensitivity : Auto for the 1st timer, later adjust for max power without falsing.
The 10" stock coil seem to be the best. Some may prefer an 8" in trashy areas. I have used a SunRay 12" to cover large area's quickly.
If you’re using an Elite or GT, use the band selection switch to reduce interference.
On the GT, I would 1st run in the “fixed” ground track mode.

Cal Jim

Sounds pretty similar to Jims.

Not always wide open, sometimes 29
IM -15
always IM with deep on most of the time.
gain 8 or 9
volume 10

I'm in ferrous sounds.

NS Andy

Not much to add to Andy`s settings Those are a winner but I always hunt in Ferrous sounds

Garrett 2500 Settings-

Relics Mode
Sensitivity 10
Threshold- slight hum
I use belltone but not neccesary
The trick with Garrett is it'll lock as you image it at 90 degrees if the cursor bounces around more than a few segments its trash. dig everything that locks on above 3 as have found many hammies in the just above foil range.
Run with the 12.5 imaging coil if possible.

Can Rod

Hey there, forgot to mention on the 2500 a very important feature. Manually Groundbalancing and use of the true all metal mode turns the 2500 into a real animal. Only 5-10 % of folks use it but it becomes a different machine. Ground balance it by bobbing it as you hold the fast track button so you get a slight positive on the downward bob just above the ground. The machine is now about 20% deeper, and you can toggle back and forth between last mode as a coin check if you wish. This becomes a lot noiser but will still ID properly. Have dug greenies at over 14 inches using the 12.5 inch coil in allmetal. HH
